There is an understanding amongst teams that as long as you don't attempt to advance the ball we won't attack your guys. It's an unwritten rule, a gentlemens agreement between coaches.
To betray that without warning is the act of bitch.
Not disagreeing with you on this because I see both sides of the argument but what I found it humorous that Dan Marino had similar thoughts on the incident of what you said here but is it really much different than this?
Marino made it clear he was spiking the ball, the defense let up and he took advantage. What if the defense had tried to blast through the line and he really was going to spike the ball? Surely people could have gotten hurt.
